WASHING-MACHINE.

Specification of Letters Patent.

Patented Feb. 22, 1921.

Application filed October 26, 1920. Serial No. 419,581.

T 0 all whom t may concern Be it knownthat I, HARRY M. TAYLOR, a citizenof the United States, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented a new and useful Washing-Machine, ofwhich the following is a specification.

This invention relates to improvements in washing machines, and pertainsmore espe.- cially to improved means for oscillating the tub in whichclothes are to be washed and which is contained internally of an uprightcasing which is open at its upper end.

One objectof this invention is to facilitate the oscillation of said tuband to reduce to a minimum/the power required for said oscillation.

Another object is to provide improved means for. minimizing vibration of,tub-oscillating mechanism. operated by a watermotor, and to have saidmotor conveniently located internally of the. aforesaid casing andadequately and inexpensively supported from the framework which saidcasing comprises.

Another object is to have the componentv members of the tub-oscillatingmeans compactly arranged and to render said means readily accessible forlubrication, simple and durable in construction, reliable in their op- Aeration, and not liable to get out of order.

With these objects in view, and to attain any other object hereinafterappearing, this.

invention consists in certain features of construction, and combinatlonsand relativearrangements of parts, hereinafter described in thisspecification, pointed out in theclaims, and villustrated in theaccompanying drawings.

In said drawings, Figure 1 is atop plan of a washing machine embodyingmy invention. Fig. 2 is a vertical section taken along the line 2-2,Fig. 1, looking inwardly. Figs. 3v and 4 are vertical sections, indetail, taken along the line 3-3 and line 4-4, respectively, Fig. 2,looking in the direction indi'- Portions are broken away in the drawingsto reduce their size, and Figs. 3 and 4 are drawn on a larger scale thanFigs. 1 and 2.

ln said drawings is illustrated a washing machine comprising an uprightcasing which is open at its upper' end and (see Figs. 1

and 2) preferably consists of framework 10 and metal plates or sheets 11covering said framework at the sides. Said casing is shown mountedoncasters 12 applied in any ap roved manner.

nternally of` said casing and surrounded by the framework 10 is aclothes-receiving tub 13 which .has a lid or cover 14 applied in anyapproved manner. Said tub is provided with two substantially horizontaltrunnions 15 and 16 which (see Figs. 1 and 3) are arranged at oppositesides respectively of and externally of the tub and in line, endwise andsupported from the framework 10. Preferably the trunnions 15 and 16respectively have bearing in journal-boxes 17 and 18 of any approvedconstruction, and the body of the tub-13 is arranged nearer thetub-surrounding framework 10 at its trunnion 16 than at the trunnion 15.The journal-box 18 (see ,F ig. 3) is rendered rigid with and supportedfrom a member 2O of said framework in any approved manner. The box 17 issupported from said framework through the medium of a substantiallyhorizontal anglebar which' is substantially at aright angle -to thetrunnion 15 and wholly'internally of the casing and arranged with onewing or member 21 thereof projecting downwardly .and. with its otherwing or member 22 pro-l jecting in the dlreotion in which said trun-Inlon projects from the body of the'tub 13. The member 22 ofsaid'angle-bar (see Fig.

2) rests at its ends on and is secured tomem-V bers 23 of the framework10.- The casing has its side in the direction of which the trunnion 15and bar-member 22 roject spaced far enough from "anglear and, from saidtrunnion to permit of the location, between saidside of the casing andthe tub 13,

of my improved tub-oscillating means herementioned side ofthe casing soas not to inj y terfere with the location of said angle-bar in proximityto the tub 13. Preferably the journal-box 17 is mounted'on the member 22of said angle-bar and secured to said member in any approved manner, andFig.3'shows said box flush at its inner end with the :"in-- wardlvfacing side of the wing 21 of said bar. Fach trunnion of the tub 13 isshown provided at its inner end with arms 26 which inforce the tub.

. The trunnion 15 is one of the component members of my improvedtub-oscillating mechanism which also comprises a substantiallyhorizontal downwardly facing reciprocatory rack 27 which is arrangedsubstantially at a right angle to said trunnion and over and spaced`from'the journal-box 17,

and consequently arran ed over and spaced from said trunnion. ttaidtub-oscillating mechanism also comprises a segmental gear 28 arrangedunder and meshing with the rack 27 and operativelyy mounted on thetrunnion 15. j

The rack 27 is operatively connected in any approved manner with awater-motor 30 supported from the framework 10 through the medium ofthe' hereinbefore'mentioned angle-bar. The construction and operation ofwater-motors are too well known to require description and illustrationin detail in this specification. Sufce it to state that 31 indicates apipe at which water under pressure is supplied to the motor, and that 32indicates a pipe at which Water is conducted from the motor. The motor30 is mounted (seeFig. 4) on and secured to the top 33 of a table whichhas one leg 34 mounted on and secured to the member 22 of the aforesaidangle-bar at a point spaced from the journal-box 17 and has another leg35which is secured to a member 36 of the adjacent portion of theframe-work 10. The

journal-box 17 (see Figs. 1, 2 and 3) is provided at its motor-faclngside with an upwardly projecting arm 38 which extends above the rack 27and is provided with an anti-friction roller 39 which is substantially`parallel with the trunnion 15 and arranged over and next said rack and,therefore arranged to retain the rack in mesh with the A gear 28. Therelative arrangement ofthe parts is such that in the horizontal positionof the tub 13, as shown in Fig. 2, the rack 27 and the engaging gear 28are in their mid position, and obviously therefore said gear and theconnected tub are oscillated alternately in opposite directions duringthe reciprocation of the rack.

Improved means for minimizing the vibration of the component members ofthe tub-'oscillating mechanism during its operation comprise two coiledsprings 40 arrack. Arrangedat the outer side of the arm 4l is a rigidlink-forming member 42 which is substantially parallel with the rack 27and pivoted centrally between its ends, as at 43, to said arm and hasits axis substantially parallel with the axis of the tub 13. Preferablythe springs 40 are attached at their outer ends to the arm 25 oflopposite end portions respectively of the wing 21 of the aforesaidangle-bar and at their inner ends to opposite ends respectively of thelinkforming member 42 and are under tension in the mid position of therack 27 and engaging gear 28, so that the one or the other springisplaced under greater tension according as the rack and gear are actuatedbeyond their mid position in the one or the other direction. Theconnection between each spring 40 and the adjacent arm 25 preferablycomprises a hook-bolt to the hook .45 of which is attached said spring,and

said arm (see Fig. 4) has a hole 46 at which the shank 47 of said boltextends loosely through said arm and outwardly beyond the outer side ofsaid arm, and a thumb-nut 48 is threaded at the outer side of said armonto said shank. Hence, only the nuts 48 on the hook-bolts requiremanipulation, during or upon the assemblage of the arts, to place thesprings 40 under the deslred tension inthe horizontal and' mid positionof the tub 13, also, to permit the location and operation of the gear 28in close proximity to the journal-box 17 the member 22 of the aforesaidangle-bar has a portion thereof bent downwardly, as at 50, along thecentral portion of the bar to positively avoid` interference by saidmember of lsaid bar with the location and operation of l the arm 41 ofsaid gear.
